So as to transmit the device of light and the device of light is transmitted using optical fiber inside light pipe.The laser peening device of nuclear reactor
An example have disclosure in Korean Patent Publication 2012-0048692.
The part irradiated for common laser peening device due to laser beam and machined surface are vertical, therefore laser beam
Irradiated along with machined surface vertical direction.The plasma produced on machined surface is possible to cause to damage to laser peening device
Wound, or because Plasma-Laser beam may be cut off.
On the other hand, for the laser peening device according to prior art, for uneven weld part and weld part
Periphery, operating personnel must directly specify laser work magnetic head (head) working path.Further, since by manpower butt welding
The shapes and sizes of socket part carry out weighing the working path so as to assignment magnetic head, thus consume more in shot-peening operation
Time, and the accuracy reduction of operation, it is impossible to complete effective shot-peening operation.
Therefore, the problem of being can solve the problem that in the urgent need to a kind of technology caused by prior art.
